The graphics are really great! I like the UI which display all the skills & parameters clearly. All the controls are intuitive and simple. The animation of red blood cell flowing in the background is awesome too!
Sometimes, the leukocytes look like trapped on the wall of the blood vessel and I got stuck by some of the debris cells at the end of the blood vessel. The shooting damage is high enough that I didn't really use the short-ranged attacks by button 1 & 2. Also, when I got too close to the leukocytes, even when I used the 2 short-ranged attacks, I got killed. If this game will be further developed, the balance of the damage of long-ranged and short-ranged attacks may need to be adjusted. Besides, may introduce different movement patterns for the leukocytes to bring more challenge to the players.
Overall, it's a great work done within 48 hours! Love your game.
